Results are in.. Used shadow protect.. set to 50GB files at a time on
the backup file side.. average throughput 23 MB/s.. finished in 4hr 25
minutes, the same time as a local backup took (this was across
gigabit).

So I guess its true.. there is something to the polution of the cache/
registry issue? Anyone have a KB article where I could find the tweak
and try this again without splitting the backup files? (Not sure what
I'm searching for exactly).

Thanks
